NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
921 PM CST Friday Feb 27 2015 


Update... 


Updated marine headlines to better fit wind forecast described in 
grids. This will add inner open waters east of the mouth of the 
Mississippi River to the advisory...and will carry exercise 
caution across remaining marine zones. 


Will also massage hourly temperature/dew point grids to fit existing 
conditions. No changes to overnight low forecast at this time. 35

Previous discussion... /issued 723 PM CST Friday Feb 27 2015/ 


Sounding discussion... 


Routine flight terminated a few miles from last nights Termination 
Point...about 2 miles north of the University of South Alabama 
Campus in Mobile. Flight reached a height of 110.5k feet or close 
to 21 miles in altitude after 105 minutes of flight. 


Sounding remains rather dry with a precipitable water value of 
0.49 inches. There was about a 4c inversion just below 900 
mb...and an isothermal layer between 780 and 680 mb. Freezing 
level was at 11k feet...and -20c was at 21.6 feet. 


Winds were light northerly in the lowest 5000 feet...became 
westerly around 7000 feet and remained generally westerly through 
100 mb. Maximum wind of 120 knots at 36.8k feet. 35 


Previous discussion... /issued 250 PM CST Friday Feb 27 2015/ 


Short term... 
clear skies continue over the area this afternoon as strong high 
pressure builds in from the north. Temperatures have struggled to 
reach the lower 50s and a few locations Haven/T even done that as 
cold air advection brings in the surge of cold air. Similar trend 
will persist overnight with another round of sub 40 degree lows and 
possibly a few locations touching freezing once again. Temperatures could 
be even colder than that but guidance showing midlevel moisture 
increasing this evening and overnight which should result in some 
clouds at around 10k feet. Thinking is that this will keep temperatures 
from falling too much. For climatology reference...these 
temperatures are still around 15 to 20 degrees below normal. 
Conditions will not be all that different tomorrow except for temperatures 
about 10 degrees warmer moisture on the rise as winds become more 
easterly. 


Long term... 
significant changes will be coming this weekend. Upper level ridge 
will be building over the Caribbean/Gulf of Mexico and pushing north 
into Gulf Coast. This will bring moisture and warmer temperatures to the 
area beginning Sunday. Highs will be coming up into the middle to upper 
60s Sunday per guidance. Rain chance is slightly more uncertain on 
Sunday as GFS has backed off by 20 to 30 percent. Did lower probability of precipitation 
some but not to that degree as European model (ecmwf) still showing quite a bit of 
activity over the area. 


Models still showing a cold front approaching the area Monday but 
stalling to the north due to loss of its upper level trough push. 
Rain chances do remain elevate with northern zones seeing higher 
probability of precipitation than coastal areas. No big changes from previous forecast for 
that or temperatures. Kept highs in the lower to middle 70s as well as 
dewpoints in the 60s. Will then be in a lull for rain Tuesday... 
though a few scattered showers possible...until the next front comes 
on Wednesday. The upper level trough behind this front looks be much 
broader and will dig further south across the southeastern Continental U.S.. could see 
a good 24 hour period of light to moderate rain. Latest model 
sounding indicate that sub freezing low level air could push in over 
southern Mississippi right before the rain finishes. If this were to 
happen...a short period of freezing rain mixed with sleet could 
occur. Too many if's at this time to be overly concerned with that 
outcome at this time. Just something to watch. 


Meffer 


Aviation... 


Low clouds with bases 016-022 should dissipate by or shortly after 
the start of the 18z taf period. Generally clear skies and excellent 
visibilities will prevail through this evening. Slightly elevated northeast 
winds 10 to 15 knots with a few gusts to near 20 knots should 
subside early this afternoon. Some middle level clouds are expected 
tonight...and this will likely keep temperatures from falling close 
enough to the dewpoints to produce fog or mist...so VFR is expected 
to prevail through 18z Saturday. 


22/dew point 


Marine... 
a reinforcing shot of cold air will continue to settle in over the 
forecast area tonight. The pressure gradient didn/T really 
relax...so had to extend the Small Craft Advisory to this afternoon with this 
morning/S issuance. Now...with nocturnal wind enhancement expected 
over offshore waters...doesn/T make sense to cancel the Small Craft Advisory for a 
short period late this afternoon before winds pick back up to above 
20 knots. Kind of in the same boat tomorrow as winds may slightly 
weaken during the day to just below criteria and then come back up 
in the evening. Winds will finally switch around to the east on 
Sunday and then southeast Monday and Tuesday as high pressure to the 
north...slides east. Forecasted middle to upper 60 degree dewpoints 
will be conducive for sea fog development next week. Strong cold 
front to bring the return of Small Craft Advisory conditions later on Wednesday.
